The rapid pace of Calgary’s expansion since the 50s continuously raised questions from academics and concerned citizens, who described it as a perfect example of urban sprawl and deemed it unsustainable from the human, economic and environmental point of view. This podcast is a series in 3 episodes that aims at exploring this question, through interviews with experts to discuss the dangers linked to this phenomenon from three different points of view: the threats towards Calgary inhabitants, biodiversity and the cultural heritage of Indigenous people. This podcast was created as part of the Canadian Wilderness Stewardship Program run by CPAWS.
